This is not true.  GPG will never use a cipher that the recipient does
not prefer.  It may not use the recipient's #1 choice, but it will
always use something from the recipient's list.

It's not always simple to calculate what cipher should be used.  For

Alice:   AES256 TWOFISH
Baker:   TWOFISH AES256

Who wins?
